Hi All,

I have seen the definition of Valve crawl in valve selection handbook by Peter Smith as "The gradual decreasing of the set pressure of spring loaded pressure relief valves from below to normal after the temperature of the spring has been raised by the fluid just discharged."

Is it from normal to below .

How can be the crawl avoided.

Thanks
